Statistics, Adjusted Statistics, and Maladjusted Statistics
American Journal of Law & Medicine, 2017Statistical adjustment is a ubiquitous practice in all quantitative fields that is meant to correct for improprieties or limitations in observed data, to remove the influence of nuisance variables or to turn observed correlations into causal inferences. These adjustments proceed by reporting not what was observed in the real world, but instead modeling

, 2011 The first example involves the real data given in Table 1 which are the results of an interlaboratory test. The boxplots are shown in Fig. 1 where the dotted line denotes the mean of the observations and the solid line the median. We note that only the results of the Laboratories 1 and 3 lie below the mean whereas all the remaining laboratories return ...

Current Protocols in Human Genetics, 2003
AbstractStatistics is a relatively new science with most of the important developments occurring within the last 100 years. The goal of this unit is to summarize some of the philosophical ideas behind statistics and to provide a general framework in the form of flowcharts for deciding which statistical test is appropriate for a given dataset and ...

Statistical Methods in the Atmospheric Sciences
, 2007Read any paper in statistical meteorology or climatology since 1995 and you are nearly certain to find a citation of the first edition of this book (Wilks 1995). This is for good reason.

Optical Society of America Annual Meeting, 1990
The balanced homodyne detector is the paradigm of phase-sensitive detection schemes in quantum optics. We study the effects of a quantum local oscillator in a coherent state for this detector when it is coupled to a single signal mode. We calculate explicit general expressions for the output statistics of the difference current of this detector ...

Pediatrics, 1989
Pediatrics, July 1988, contained two articles, each of which had a "negative result" as its primary conclusion. That is, in each study the authors looked for a statistically significant difference between two groups and found none. A third study? in the same issue also concluded "no difference" in an important comparison between its study and control ...

Statistical models and statistical inference
1981In the previous chapter we have seen how a simple statistical model can be fitted to data by estimating the unknown parameters and then making checks with residuals. After we have done this, various questions can be answered in terms of the fitted model.

Order Statistics and Nonparametric Statistics.
1978Abstract : The research reported falls under the headings: (a) order statistics; (b) competing risks; (c) nonparametric statistics, and (d) cyclic designs. (a) Concomitants of order statistics were introduced and studied as a class, and applications in selection and double sampling provided. The robustness of various estimators of location and scale in
